[Live-devel] live stream & visual_object_sequence_start_code

[cristafol]

Hi all,
 
Thanks Ross, I am progressing, but I need even your help. This time a
have read all FAQ section, sorry.
The question is, It seems that for SDP works, I have to call the
function auxSDPLine, that get two informations of
MPEG4VideoStreamDiscreteFramer:
frameSorce->profile_and_level_indication()
frameSorce->getConfigBytes(configLength)
 
In  MPEG4VideoStreamDiscreteFramer::afterGettingFrame1 there is the
assign of fProfileAndLevelIndication, but in short, how can I generate
the VISUAL_OBJECT_SEQUENCE_START_CODE that seems indispensable for SDP
to works?.
 
I only have MPEG4 frames that generate ffmpeg with the function
"avcodec_encode_video".  Is Visual_object_sequence_start_code related
with the stream header ( function "av_write_header" of fmpeg). But a m4v
file do not have header, no?.  Please help!!!
 
Best Regards,
Cristobal Belles
